I-Alkyl Polyglycosides-Izixazululo Ezintsha Zezicelo Zezolimo

Ama-Alkyl polyglycosides ayaziwa futhi atholakala kubakhiqizi bezolimo iminyaka eminingi. Kukhona okungenani izici ezine ze-alkyl glycosides ezinconyelwe ukusetshenziswa kwezolimo.

Okokuqala, kunezindawo ezinhle kakhulu zokumanzisa nokungena. Ukusebenza kokumanzisa kubalulekile kumsunguli wezinto ezomile zezolimo futhi ukusabalala endaweni yezitshalo kubalulekile ekusebenzeni kwezibulala-zinambuzane eziningi nezithasiselo zezolimo.

Okwesibili, ayikho i-nonionic ngaphandle kwe-alkyl polyglycoside ebonisa ukubekezelelana okuqhathaniswa nokugxila okuphezulu kwama-electrolyte. Lesi sakhiwo sivula umnyango wezinhlelo zokusebenza ebezingafinyeleleki ngaphambilini kuma-nonionics ajwayelekile nalapho ama-alkyl polyglycosides ahlinzeka ngezici ezifiselekayo zama-nonionic surfactants phambi kwezibulala-zinambuzane ezine-ionic ephezulu noma ukugxila okuphezulu komanyolo we-nitrogen.

Okwesithathu, ama-alkyl polyglycosides anohlu oluthile lobude beketanga le-alkyl awabonisi ukunyibilika okuphambene nezinga lokushisa elikhulayo noma isici esithi "cloud point" sama-alkylene oxide asekelwe kuma-nonionic surfactants. Lokhu kususa umkhawulo obalulekile wokwakheka.

Okokugcina, amaphrofayili e-ecotoxicity we-alkyl polyglycosides aphakathi kwalawo ahambisana kakhulu nemvelo awaziwayo. Ingozi ekusetshenzisweni kwazo eduze nezindawo ezibucayi, njengamanzi angaphezulu, iyancipha kakhulu uma kuqhathaniswa nama-alkylene oxide asekelwe kuma-nonionic surfactants.

Enye yentuthuko ebaluleke kakhulu emlandweni wakamuva wemithi yokubulala ukhula ukwethulwa kwezigaba ezintsha ezimbalwa zemikhiqizo efakwa ngemuva. Ukufakwa kwangemuva kwenzeka ngemva kokuba isilimo osifunayo sesimile futhi sisesigabeni sokuqala sokukhula. Le nqubo ivumela umlimi ukuba abone ngokuqondile futhi aqondise uhlobo lokhula oluhlukumezayo esikhundleni sokulandela umzila ophuthumayo ofuna ukubikezela ukuthi yini engase yenzeke. Le mithi emisha yokubulala ukhula ijabulela amanani aphansi kakhulu wokufaka isicelo ngenxa yomsebenzi wayo ophezulu. Lokhu kusetshenziselwa ukonga ekulawuleni ukhula futhi kuvumelana nemvelo.

Kutholwe ukuthi umsebenzi wemikhiqizo eminingi yale mikhiqizo ngemuva kokufakwa kunamandla ukufakwa kumxube wethangi lomuntu osebenza ngaphandle kwe-nonionic. I-Polyalkylene ethers isebenza kahle le njongo. Kodwa-ke, ukwengezwa komanyolo oqukethe i-nitrogen nakho kuyazuzisa futhi ngokuvamile amalebula e-herbicide atusa, acacise ngempela, ukusetshenziswa kwazo zombili izithasiselo ndawonye. Kulezi zixazululo zikasawoti, i-nonionic evamile ayibekezeleleki kahle futhi "ingaphuma" esixazululo. Inzuzo ezuzisayo ingathathwa ngokubekezelela usawoti okuphezulu kochungechunge lwe-AgroPG surfactants. Amaconcentrations we-30% ammonium sulfate angengezwa ku-20 % wezixazululo zalawa ma-alkyl polyglycosides futhi ahlale efana. Amaphesenti amabili ezixazululo ahambisana nokufika ku-40% ammonium sulfate. .

Inhlanganisela yezinto ezisanda kuxoxwa ngazo (ukumanzisa, ukubekezelela usawoti, i-adjuvant kanye nokuhambisana) inikeza ithuba lokucabangela inhlanganisela yezithasiselo ezingakhiqiza ama-adjuvants asebenzayo amaningi. Abalimi nabafake izicelo ngokwezifiso badinga kakhulu ama-adjuvants anjalo ngoba aqeda ukuphazamiseka kokulinganisa nokuhlanganisa ama-adjuvants amaningana. Kunjalo, lapho umkhiqizo upakishwe ngenani elinqunyelwe kusengaphambili ngokuhambisana nezincomo zokulebula zomkhiqizi wezibulala-zinambuzane, lokhu futhi kunciphisa amathuba okuxuba amaphutha. Isibonelo senhlanganisela enjalo yomkhiqizo we-adjuvant amafutha e-petroleum spray kuhlanganise ne-methyl ester noma uwoyela wemifino kanye ne-adjuvant yesisombululo somanyolo we-nitrogen ogxilile ohambisana ne-alkyl polyglycosides. Ukulungiswa kwenhlanganisela enjalo nokuzinza okwanele kwesitoreji kuyinselele enkulu. Imikhiqizo enjalo manje yethulwa emakethe.

Ama-Alkyl glycoside surfactants ane-ecotoxicity enhle. Amnene ngokwedlulele ezintweni eziphila emanzini futhi ayabola ngokuphelele. Lezi zici ziyisisekelo salezi zinto ezisetshenziswayo ukuze zibonwe kabanzi ngaphansi kwemithetho ye-US Environmental Protection Agency. Kungakhathaliseki ukuthi umgomo uwukwenza izibulala-zinambuzane noma ama-adjuvant, kuyaqashelwa ukuthi i-alkyl glycosides inikeza imisebenzi ngezingozi ezincane zemvelo kanye nokusingatha ngezinqumo zazo, okwenza ukukhetha kube ukwakheka okunethezeka kakhudlwana.

I-AgroPG alkyl polyglycoside iyisisetshenziswa esisha, esithathwe ngokwemvelo, esibolayo, futhi esinobungani bemvelo esinochungechunge lwezimpawu zokusebenza, okufanele ukucatshangelwa futhi sisetshenziswe ekuhlanganiseni okuthuthukisiwe kwezibulala-zinambuzane nemikhiqizo eyisiza yezolimo. Njengoba umhlaba ufuna ukwandisa umkhiqizo wezolimo kuyilapho unciphisa imiphumela emibi emvelweni, i-AgroPG alkyl polyglycosides izosiza ekuqinisekiseni lo mphumela.
